I use the John William Barr vs the John Henry Barr because various records refer to him as John WILLIAM Barr. For example the birth records of some of his children read John William Barr. I cannot find a record that gives the Henry.
Marker at cemetery indicates that he was 60 years, 3 months, and 26 days old when he died on 30 June 1891. If this is correct he was born 04 Mar 1831.

Buried:
Junitia Burdette read most of the cemeteries in Mason County. She has commented that she believes Mary Catherine Rayburn-Barr was buried at Preston Love Cemetery.

Died:
Mason County CH Records indicate she was 21 when she died. In the 1950 Census she is 17 living with John at his Mothers's home.
Son George was born in Apr of 1953. The Courthouse Records that were copied from the original records were alphabetized by last name. Somewhere in the copying dates were omitted. The dates jump from February to September. Instead of the actual date they inserted the quote mark.
